Abstract

Rotating stirring device, particularly for mixing heterogeneous systems in mechanical stirred reactors, fit to be joined to a drive shaft coaxial with respect to the device rotation axis, which comprises a plurality of extended and substantially C-shaped stirring elements, symmeterically arranged with respect to the rotation axis and joined each other at the respective ends correspondently with the rotation axis. Such a device permits to obtain a very efficient material exchange among different phases, substantially remaining constant with the increase of the volume of the mass put under stirring, and it is also characterized by high mixing homogeneity and particularly low shear stress values.
